type print("hello") then CTRL+V and then delete once, the command line looks ok, but there's a bizarro character at the end.

This is with Ubuntu terminal console.

Code
print("hello")
error: 	[string "print("hello")"]:1: unexpected symbol near '<\127>'

Ctrl-V means "interpret the next character literally", so Ctrl-V Ctrl-C will type a literal ETX character rather than sending SIGINT, Ctrl-V Delete will type a literal DEL rather than deleting the previous character, etc.
